| Outline of Final Research Achievements |
Precise optical frequencies can be derived from laser-cooled ions in ion traps. The single-ion optical clock exploits this feature. However, the strategy for extending it to multiple-ion versions to improve the performance has not been known until recently. We have shown theoretically and experimentally that such extensions are feasible with implementations such as the superradiant ion clock using thousands of ions and multi-ion clock based on tens of ions. These new clocks will lead to higher precision of the GPS system and faster transfer rates of optical communications in future.
